This application claims priority to U.S. Provisional Application Ser. No. 61/903,362, filed Nov. 12, 2013, which is incorporated by reference as if fully set forth herein.

FIELD OF THE INVENTION

The present invention relates to systems and methods for utilizing theacrine alone and in combination for use in providing physiological benefits. More particularly, the invention relates to theacrine and other naturally occurring compounds, whether produced synthetically or harvested from natural sources, and use of these chemical compounds to provide physiological benefits, which may vary according to theacrine concentration and the presence of synergists and antagonists.

BACKGROUND OF THE INVENTION

Tea is one of the most widely consumed products in the world. Tea and the different varieties of tea have been extensively studied. Many epidemiologic and preclinical studies suggest that drinking tea may reduce the risk of cancer and cardiovascular disease. Theacrine, an alkaloid purine similar to caffeine, is relatively rare and only found in a few varieties of tea (kucha tea, genus Camellia), the fruit cupuaçu, and other plants related to coffee and cacao (genera Coffea and Theobroma), such as Coffea liberica, Coffea dewevrei, Coffea abeokutae and Theobroma grandiflorum.

1,3,7,9 tetramethyluric acid, commonly known as theacrine, was not studied until around 1975. However, it has been known of since about 1937, when it was detected in dry, decaffeinated Camellia sinensis tea leaves. At this time, the Camellia assamica var. kucha variety of tea is the primary source of naturally occurring theacrine and produces the chemical in higher concentrations than other known plants. Interestingly, theacrine has not been detected at all in more traditional teas strains. It is believed to be formed by methylation of caffeine and may be an intermediary in the production of liberine or other purines. Its natural function, if any, remains unknown. Theacrine has garnered attention only relatively recently, and often only as a secondary consideration when analyzing other compounds. Some studies suggest it may have beneficial qualities, such as serving as an effective antioxidant, anti-inflammatory and may have anti-obesity properties.

In the studies involving theacrine, beneficial effects may be at least partially attributable to an assortment of purine alkaloids and phenolic compounds. The more common tea-related purine alkaloids include caffeine, theobromine, theophyline and theacrine. The major tea phenolic compounds are gallic acid and eight naturally occurring tea catechins, including (+)-catechin (C), (−)-epicatechin (EC), (+)-gallocatechin (GC), (−)-epigallocatechin (EGC), (−)-catechin gallate (CG), (−)-gallocatechin gallate (GCG), (−)-epicatechin gallate (ECG) and (−)-epigallocatechin gallate (EGCG).

Many different biologic and physiologic activities have been attributed to tea and its various components. However, only a few of its components have been studied in depth. Caffeine is by far the most studied, and the most commonly used stimulant found in tea. Theacrine appears to have an opposite effect, despite being very similar in chemical structure. Recent experiments have shown that theacrine exhibits a variety of activities, some of which seem inconsistent.

In the past several years, there has been a substantial shift in public opinion toward using naturally occurring chemical compounds for a variety of purposes, instead of synthetic chemicals. For example, a wide variety of natural chemicals are now commonly used as sedatives, e.g. valerian root and chamomile, anti-depressants, e.g. St. John's wort, stimulants, e.g. caffeine, and concentration, e.g. ginseng. In general, naturally occurring compounds may be easier for the body to digest and interact with and may include minimal and less severe side effects.

It is therefore desirable to identify naturally occurring chemical compounds and mixtures thereof that may provide benefits. It is also desirable to provide chemical compounds and mixtures thereof that may be used to provide a variety of benefits, varying by concentration, thus requiring production or harvesting of fewer materials.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a chemical composition comprising theacrine, either naturally or synthetically produced, and optionally other chemicals, including theacrine congeners or analogs, to provide a plurality of desirable effects. Theacrine analogs may include, but are not limited to, caffeine, methyl caffeine, theobromine, theophylline, liberine and methylliberine, and their variants. Other suitable actives may include one or more ergogenic or nootropic compounds such as CDP choline, alpha-GPC, choline bitartrate, St John's Wort, sulbutiamine, and the like.

Theacrine exhibits a wide variety of effects depending on dosage. The presence of other ingredients may also modulate its effects. It may be used to promote calm or focus and to relax, but also may be used to enhance energy and stamina. It may also serve as an antioxidant and an anti-inflammatory.

In one embodiment, theacrine may be used to modulate stimulants, to provide heightened energy without heightened anxiety or nervousness. There may be variability among individuals, as described herein.

In another embodiment theacrine may be used as a mild sedative or relaxant.

In a further embodiment, theacrine may be used to promote weight loss, act as an antioxidant and as an anti-inflammatory. Theacrine may be used transdermally to enhance one or more of these effects.

In one embodiment, a dietary supplement comprising about 5 mg to about 850 mg theacrine, either natural or synthetic, is provided.

In another embodiment, a method of treatment for improving physical performance or energy in an individual is provided. Said method involves providing the individual with a composition comprising about 5 mg to about 850 mg of theacrine, either natural or synthetic, wherein upon administration of the composition the individual experiences improvement of at least one of mood, energy, focus, concentration or sexual desire or a reduction of at least one of anxiety or fatigue. In another embodiment, a second compound such as caffeine may also be administered in the composition.

It is therefore an object of the present invention to provide compositions including theacrine capable of imparting a plurality of positive effects.

It is another object of the present invention to provide congeners, derivatives and iterations of theacrine and synthetic chemical equivalents of theacrine.

It is another object of the present invention to provide agglomerated theacrine, theacrine salts, microencapsulated, liposomal or esterified theacrine.

It is another object of the present invention to provide theacrine combined with glycerides, propylene glycol, polyethylene glycol (PEG), lauroyl macrogol, lauroyl macrogol derivatives and co-crystallization products of theacrine.

These and other objects and advantages of the present invention will become apparent from a reading of the attached specification and appended claims. There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

DETAILED DESCRIPTION OF THE INVENTION

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

Disclosed is an invention relating to uses of theacrine, also known as 1,3,7,9-tetramethyluric acid, Temurin, Temorine, Tetramethyluric acid, Tetramethyl uric acid and 1,3,7,9-tetramethylpurine-2,6,8-trione. Theacrine may be produced synthetically or may be isolated from a natural source. Theacrine isolated from a natural source may be purified to 95% or greater. Optionally, less purification may be used such that theacrine accounts for 50%, or even less, of the material. In some embodiments, it may be preferable to utilize theacrine isolated from a natural source which may include other congeners of theacrine typically found in theacrine isolates.

In one embodiment, theacrine may be combined with other chemical compounds to provide a plurality of positive effects on a human or other animal. By altering the dosage of theacrine and/or chemical compounds it is combined with, various physiological effects may be selected for. The compositions may provide primarily a single benefit, or may provide multiple benefits simultaneously.

In another embodiment, theacrine may be used at lower dosage levels and/or in conjunction with compounds that modulate or antagonize its activity. Such compositions may induce an improved mood, higher energy, a reduction in fatigue, increased focus, increased concentration, increased mobility, decreased appetite, and increased stamina.

An advantage of using the invention may be the reduced likelihood that a person develops a tolerance to chemical compositions in accordance with the principles of the invention. That is, a person may not become desensitized to the effects induced.

In another embodiment, theacrine may be used at higher dosage levels and/or with synergistic compounds. These compositions may increase a person's basal/resting metabolic rate, increase thermogenesis, decrease appetite, enhance cognitive performance, increase Alpha wave brain activity, and/or induce euphoria. Without being bound by theory, the inventors believe that at higher dosage levels, theacrine may be noradrenergic and dopaminergic, and may exhibit increased adenosine receptor inhibition.

In another embodiment of the invention, theacrine may be combined with ephedrine, caffeine, salicylic acid or the like. These may be used to either modulate the more sedative effects of theacrine or optionally to interact synergistically with the more stimulating effects of theacrine. For example, theacrine may be combined with caffeine in order to modulate the excessive stimulatory effects of caffeine, thereby stabilizing heart rate and other metabolic activity. That is, a combination of theacrine and caffeine may result in a composition that imparts the increased focus and energy induced by caffeine, but without the higher heart rate and blood pressure due to modulation of caffeine by theacrine. Thus the combination may result in heightened awareness and calmness without the jitters caffeine may cause.

Theacrine and caffeine administered in combination has unexpected effects. Indeed, it has been unexpectedly found that a combination of theacrine and caffeine administered to human subjects results in increased levels of focus, concentration and energy as measured by 100 mm VAS scales while also decreasing measures of anxiety, irritability or feelings of overstimulation. Such decrease in anxiety, irritability, jitters and/or feelings of overstimulation is reflected by patients on standardized 100 mm VAS at durations of 30 minutes, 60 minutes, 120 minutes and 180 minutes as compared with administration of caffeine alone. The combination also exhibits a prolonged duration of action in increased energy, focus and/or concentration as compared to either caffeine or theacrine alone.

Furthermore, theacrine also has unexpected effects on the development of tolerance and habituation of caffeine. In a fourteen day study of repetitive dosing of theacrine and caffeine, it was found that the subjects maintained heightened psychometric indices of energy, focus, concentration, motivation to exercise, motivation to accomplish and finished tasks, and improved mood at Day 14 as compared to caffeine alone, and absolute levels of energy and motivation were greater than with theacrine alone. Those taking theacrine alone still maintained elevated subjective energy, focus, concentration, motivation to exercise, motivation to accomplish and finish tasks, sexual desire and improved mood with decreased anxiety as compared to Day 1. Subjects taking caffeine alone saw decreasing levels of energy, focus and concentration by Day 5 of the study and had increased anxiety scores throughout the study.

In another embodiment of the invention, theacrine may be combined with one or more bioavailability enhancers, including for example bioperine, piperine, black pepper, bergamottin, dihydroxybergamottin (CYP3A4 inhibitors), flavonoids (including hesperidin, naringin, tangeritin, quercetin and nobiletin both in isolation and in combination), pterostilbenes, fisetin, nanoencapsulation, microencapsulation, liposomes and/or phytosomes. Which enhancers are combined with theacrine may depend on which qualities of theacrine are desired for a particular use.

In another embodiment of the invention, theacrine may be introduced using one or more delivery methods, including, for example transdermal patches and/or creams, ready to mix powders, intravenous methods, capsules, tablets, liquid (including liquids for mixing with other beverages), softgels, shot format, and/or cosmetic applications including soaps, lotions and shampoos. Theacrine's anti-inflammatory qualities may be desired for a variety of topical applications.

In another embodiment of the invention, theacrine may be used to provide sports performance enhancers that may reduce fatigue, improve mobility, and improve alertness.

In another embodiment of the invention, theacrine may be used as a topical agent for incorporation into body creams or lotions to produce a cream or lotion for lightening skin, firming skin, and/or improving skin elasticity. A theacrine topical agent may also be used to promote localized transdermal fat loss. Theacrine may also be used in a cream or lotion to promote localized enhanced metabolism and/or enhanced thermogenesis.

In another embodiment of the invention, theacrine may be combined with one or more of an analgesic, for example ibuprofen or salicylic acid, anti-inflammatory agents, salicin, fish oil (omega-3 fatty acids and specialized, small lipid pro-resolving derivatives), tart cherry, krill oil, astaxanthin, proteolytic enzymes, glucosamine sulfate, chondroitin sulfate, MSM (methylsulfonylmethane), SAMe (S-adenosylmethionine), ASU (avocado-soybean unsapponifiable fraction), cetyl myristoleate, Dolichos falcate and/or triterpenoids.

Theacrine itself can reduce biomarkers of inflammation in humans in response to acute inflammatory stressors (e.g., intense exercise) or chronic consumption. Theacrine is shown to decrease C-reactive protein (CRP), Erythrocyte sedimentation rate (ESR), interleukin-6 (IL-6) and TNF-alpha.

In another embodiment of the invention, theacrine may be combined with extracts from one or more of Acacia catechu, Andrographis paniculata, Scutalleria baicalensis, agmatine sulfate, Stinging Nettle, Sea Buckthorn, curcumin, Cissus Quadrilangularis, Boswellia Serrata, Wasabia japonica (wasabi extract for Tea Tree Oil), Emu Oil, Arnica, Mangifera indica L. (Anacardiaceae), Lagenaria breviflora, and/or Zingiber officinale (ginger & gingerols/shogaols). Such a combination may be used in, for example, methods of augmenting and enhancing pain modulation, and controlling the inflammatory response.

In another embodiment of the invention, theacrine may be combined with one or more metabolic enhancers including hoodia gordonii, caffeine, yohimbine, synephrine, theobromine, flavonoids, flavanone glycosides such as naringin and hesperidin, tocopherols, theophylline, alpha-yohimbine, conjugated linoleic acid (CLA), octopamine, evodiamine, passion flower, red pepper, cayenne, raspberry ketone, guggul, green tea, guarana, kola nut, any beta-phenethylamines, Acacia rigidula, and/or forskolin (Coleus forskohlli). Such a combination may be used in, for example, methods of enhancing 1) thermogenesis/fat and carbohydrate metabolism; 2) fat loss, weight management and improving body composition (loss of body fat, while retaining or sparing lean body mass/fat free mass/muscle); and/or 3) appetite control/appetite modulation.

Combinations of theacrine and, for example, caffeine, theobromine, or flavanone glycosides such as naringin or hesperidin, upon administration to subjects show decreased VAS 100 mm ratings of perceived physical exertion with exercise as compared to ingredients alone. Theobromine is used by some for improvement of breathing or a subjective feeling of improved breathing, but is also known to increase feelings of anxiety, jitters and an elevated heart rate in some subjects. A combination of theobromine and theacrine retains the beneficial effects while reducing the unwanted anxiety, jitters and/or elevated heart rate effects.

In another embodiment of the invention, theacrine may be combined with anti-fatigue, focusing and/or energy enhancing ingredients including caffeine, theobromine, theophylline, synephrine, yohimbine, rhodiola, ashwagandha, ginseng, ginkgo biloba, siberian ginseng, astragalus, licorice, green tea, reishi, dehydroepiandrosterone (DHEA), pregnenolone, tyrosine, N-acetyl-tyrosine, glucuronolactone, taurine, choline, CDP-choline, alpha-GPC, acetyl-L-carnitine, 5-hydroxytryptophan, tryptophan, any beta-phenethylamines, Sceletium tortuosum (and Mesembrine alkaloids), Dendrobium sp., Acacia rigidula, PQQ (Pyroloquinoline quinone), Ubiquinone(ol), nicotinamide riboside, picamilon, Huperzine A (Chinese clubmoss) or Huperzia serrata, L-dopa, Mucuna pruriens, forskolin (Coleus forskohlli). Such a combination may be used in, for example, methods for enhancing cognitive function, including focus, concentration, sustained attention, working memory, choice and non-choice reaction time, executive function, verbal and non-verbal learning, visuospatial memory and verbal fluency.

In a further embodiment, theacrine may be combined with a nutritional cholinergic ingredient such as 2-(dimethylamino)ethanol (DMAE), DMAE bitartrate, choline bitartrate, alpha-GPC (alpha-glycerophosphorylcholine), Huperzine A, CDP choline, or combinations thereof. One of skill in the art will recognize that these are merely examples of cholinergic ingredients and that other such cholinergic ingredients not listed are also contemplated by the present invention. The combination of a nutritional cholinergic ingredient with theacrine can result in a synergistic effect of increased psychometric measures for attention, focus and concentration beyond either the theacrine alone or cholinergic ingredient alone.

In another embodiment, any of the above combinations may be used with an isomer of, congener of, derivative of and/or a metabolite of theacrine such as, for example, liberine or methylliberine. Other suitable examples include methylated theacrine, nitrate salts of theacrine, oxidized theacrine, reduced theacrine and/or theacrine salts. Agglomerated theacrine, microencapsulated theacrine, liposomal theacrine, esterified theacrine, theacrine glycerides, and mixtures of theacrine with propylene glycol, lauroyl Macrogol, polyethylene glycol, theacrine derivatives, and/or theacrine co-crystallization products may also be used in accordance with the principles of the invention. Such use of these, as well as co-crystals or other conjugates (such as quercetin or pterostilbenoids), theacrine salts including citrate, salicylate, malate, tartrate, fumarate, succinate, nitrate, sulfate, phosphate and the like, or PEG-ylated (Macrogol) preparations may increase the functional efficacy of the theacrine.

In another embodiment, congeners of theacrine, for example catechins and other flavonoids, may be used an isolated, either independently or in combination with theacrine-based compositions.

The dosage of theacrine may range from about 5 mg to about 850 mg. In another embodiment, the range may be from about 65 mg to about 300 mg. In relation to the weight of the human subject, in one embodiment the dosage may be expressed as about 0.75 mg/kg of body weight to about 3 mg/kg of body weight. In initial trials the human ED90 appears to be about 1 mg/kg to about 3 mg/kg.

In one aspect of the invention, the theacrine may be administered with caffeine. When administered with caffeine, the ratio of caffeine to theacrine, weight to weight, may range from about 0.5:1 to about 50:1, and in another embodiment, from about 1:1 to about 10:1, and in a further embodiment, from about 2:1 to about 4:1. In administration, the theacrine may be administered in an amount of about 5 mg to about 800 mg with caffeine amounts ranging from about 25 mg to about 650 mg. In another embodiment the theacrine may be administered in an amount of about 5 mg to about 650 mg with the caffeine, and in other embodiments may be any amount in that range. Such administration provides an increase, as measured by 100 mm VAS scales, in at least one of focus, concentration and energy, while also providing a decrease in at least one of anxiety, irritability, and feelings of overstimulation. Recommended dosages expressed in terms of amount per body weight can range from about 0.75 mg/kg to about 3 mg/kg of theacrine when administered in combination with caffeine, although theacrine may be administered in the ranges described above up to about 850 mg regardless of whether it is administered in combination with caffeine.

The invention may be used for the treatment of a variety of conditions, such as improvement of mood, energy, focus, or concentration. The invention may also promote a reduced appetite, reduce the perceived exertion from exercise, decrease the discomfort associated with intense exercise, and may also improve sexual desire.

EXAMPLES Example 1

In order to examine the beneficial experiential effects and psychometric properties of theacrine supplementation in healthy subjects, explore optimal dosing and potential cumulative effects in a healthy human cohort with a 7-day, sub-acute repetitive dosing protocol, and acquire preliminary data on various biomarkers of safety and tolerability, an experiment was performed.

15 healthy subjects (mean±SD age, height, wgt, BMI: 28.3±6.1 y, 175.7±11.5 cm, 89.8±21.7 kg, 29.1±4.7) ingested 200 mg of TeaCrine™ (Compound Solutions, Inc., Carlsbad, Calif.) (TC) or Placebo (PLA). Anchored VAS questionnaires were used to detect changes in various aspects of physical and mental energy and performance; side effect profiles, hemodynamics and biochemical markers of safety were also collected over a 3-hr post-dosing period. A subset of 6 subjects underwent a separate 7-day, open-label, repeated dose study comparing 100 mg, 200 mg and 400 mg of TC.

The experiment was a randomized, placebo-controlled, double-blind, within-subject crossover clinical trial (for N=15 study). A further subset study was open-label, sub-acute (7-day), repetitive dosing trial (for N=6 subset).

Six (6) subjects provided written and dated informed consent to participate in the 7-day repetitive dosing study between Dec. 15, 2012 and Feb. 21, 2013. A separate cohort of fifteen (15) subjects provided written and dated informed consent for the acute dose, placebo-controlled, crossover clinical trial. All subjects were in good health as determined by physical examination and medical history, between the ages of 18 and 45 (inclusive). Subjects' caffeine intake from foods/beverages was limited to <300 mg daily. Subjects were willing and able to comply with the experimental and supplement protocol.

Excluded subjects included subjects who were pregnant or lactating, subjects with a history of hepatorenal, musculoskeletal, autoimmune, or neurologic disease, diabetes, thyroid disease, adrenal disease, hypogonadism, inborn error of metabolism, personal history of heart disease, high blood pressure (systolic>140 mm Hg & diastolic>90 mm Hg), psychiatric disorders, cancer, benign prostate hypertrophy, caffeine sensitivity, gastric ulcer, reflux disease, or any other medical condition deemed exclusionary by the medical staff, subjects currently taking thyroid, hyperlipidemic, hypoglycemic, anti-hypertensive, anti-coagulant medications or OTC products containing pseudoephedrine or other stimulants, subjects who had used any weight-loss supplements within 30-days prior to the study, subjects who had gained or lost more than 10 lbs within the past 30 days, subjects who drank more than one cup of percolated coffee or 2 cups of tea per day, subjects who smoked or had quit smoking within the past six months, subjects who had a known allergy to any of the ingredients in the supplement or the placebo, and subjects who did not demonstrate a verbal understanding of the Informed Consent document.

The study did not incorporate a dietary intervention (other than supplement/placebo ingestion). Subjects were instructed to complete a 24-hr diet record prior to their first laboratory visit, and duplicate that 24-hr diet prior to each subsequent laboratory visit. The study also did not incorporate any physical activity intervention. Subjects refrained from exercise and/or heavy physical activity the day prior to each laboratory visit.

Physical activity levels and health history were determined using standardized questionnaires. Heart rate and blood pressure were measured using an Omron HEM-780. Standing height was determined using a wall-mounted stadiometer. Body weight was measured using a Seca 767™ Medical Scale. A 100 mm anchored VAS questionnaire for energy, fatigue, and concentration was distributed at each acute lab session; additional VAS questionnaires were distributed for the daily assessment over a 6-hour period during the 7-day subset study. Quest Diagnostics (Pittsburgh, Pa.) was utilized to transport and analyze all blood samples. For each laboratory session, subjects reported to the lab well hydrated, 10-12 hours postprandial, and at least 24-hours after their last exercise session.

Statistical Analyses:

Descriptive statistics (mean, median, SD, 95% CIs) were used to quantify subjects physical characteristics. RM ANOVA, as well analyses of co-variance (ANCOVA), using baseline scores as the co-variate (respectively), were used to analyze between trial differences. Alpha was set to 0.05 (P≤0.05) for statistical significance, and <0.10 for trends. Effect sizes were also calculated. Upon arrival for the first testing session, subjects were randomly assigned to receive their respective supplement/placebo. Each subject ingested the sponsor recommended dosage of their respective supplement (1 capsule prior to schedule of assessments). Supplements were prepared in capsule form and packaged in coded generic containers for double-blind administration.

Results:

The 200 mg dose of TC caused significant improvements in energy (TC: +8.6% vs. PLA: −5.7%, P=0.049) and reductions in fatigue (TC: −6.7% vs. PLA: +5.8%, P=0.04). A trend for improved concentration was also noted (TC: +2.4% vs. PLA: −1.3%, P=0.07). No changes in systemic hemodynamics or side effect profiles were noted. The N=6 cohort study demonstrated moderate to large effect sizes (0.50 to 0.71) with the 200 mg dose of TC over a 7-day period of assessment for the following subjective measures: energy, fatigue, concentration, anxiety, motivation to exercise and libido.

The results of the experiment are also shown graphically in FIGS. 2 through 7.

As shown in FIG. 2, individuals who were administered theacrine reported higher levels of energy at each time increment measured. FIG. 3 shows that while individuals given the placebo reported higher fatigue at 60 minutes after administration, those administered theacrine reported lower levels of fatigue. FIGS. 4 and 5 show that no substantial change in systemic hemodynamics occurred.

FIGS. 6 and 7 show the results of the N=6 cohort study. With a 200 mg dose of theacrine over a 7 day period of assessment, it was observed that theacrine has a positive effect on each of energy, fatigue, concentration, anxiety, motivation to exercise, and libido. That is, fatigue and anxiety were decreased substantially, while energy, concentration, motivation to exercise and libido were increased substantially.

Thus, the experimental data shows that theacrine supplementation appears to favorably impact several subjective and psychometric indices of energy and fatigue. These findings, as well as the potential cumulative effects on focus, concentration, and libido are worthy of future study.

Although previously published animal data suggested much larger doses of “TC” would be necessary to exert its neurophysiological effects, this first-in-human data suggests much lower doses of 1.5 mg to 2.5 mg/kg bodyweight (for example, approximately 200 mg in a 100 kg individual) provide optimal benefit. Follow-up studies should confirm these results, explore other objective measures of physical and cognitive function, and clarify the mechanisms by which theacrine exerts the observed salutary effects.

Routes of Administration

The compounds may be administered by any route, including but not limited to oral, sublingual, buccal, ocular, pulmonary, rectal, and parenteral administration, or as an oral or nasal spray (e.g. inhalation of nebulized vapors, droplets, or solid particles). Parenteral administration includes, for example, intravenous, intramuscular, intraarterial, intraperitoneal, intranasal, intravaginal, intravesical (e.g., to the bladder), intradermal, transdermal, topical, or subcutaneous administration. Also contemplated within the scope of the invention is the instillation of theacrine in the body of the patient in a controlled formulation, with systemic or local release of the drug to occur at a later time. For example, the drug may be localized in a depot for controlled release to the circulation.
